Well thanks Holly for your reply. Nice to get an opinion from a WG. I'm sure other WG might react differently, but thanks for your input.
I can understand why a WG might not want to show face pic (not because they are ugly), but I do tend to go for the ones with a face pic because I would feel bad walking. I feel bad because I have potentially taken up an hour of their time, and for them I'm sure time is money. I have had bait and switch before, twice. Once it was a same WG that I have seen before (bad attitude problem so I walked 2nd time), the other was actually a brothel and I was offered someone else (2 to choose from in fact). Probably should have walked because of risk etc, but both girls were not bad looking and my cock overruled my brain.
My other "risky" ones (no face pic) but with good FB and FR turned out to be ok.
The last time I know I should have walked but didn't was partly because I know there's someone else in the house. The bedroom door was opposite the entrance. However the other person is in behind the second door, whcih also opens to the hallway. I feared that this might be a pimp (she was an EE girl) and I might get problem if I walk.
I try to choose wisely nowadays. Face pic, FB, FR are essential in limted experience. I tend not to go to ones with face pic unless very cheap and got some FB. But then I guess they are cheaper for a reason. Using this principle I have had some good ones (including EE girls)... and some not so good ones (including UK girls). Mostly because of attitude problem, rather than face. Only found out about the attitude problem during the punt though. Lessons learned.
May I also ask whether it is normal for the WG to have someone else in the house during a punt (in another room being quiet of course) to act as security for the WG?
